Each WGS satellite has a launch mass of around 5,987 Kilograms and is based on Boeings BSS-702HP satellite platform. [1] The system is composed of the Space Segment satellites, the Terminal Segment users and the Control Segment operators.[2]. Core U.S. MILSATCOM will span just 14 satellites by 2020 [Advanced EHF (AEHF): 4, Wideband Global SATCOM (WGS): 6, Mobile User Objective System (MUOS): 4]. GBS also utilizes the Wideband Global SATCOM (WGS) satellites. Space Systems Command announced the milestone Feb. 1. This high-capacity satellite communications system is intended to support the warfighter with newer and . What is Wideband Global SATCOM? - everything RF The WGS-6 was delivered to the US Air Force in December 2013. Animation Speed. The Global Broadcast Service [GBS] augments and interfaces with other communications systems to provide a continuous, high-speed, one-way flow of high-volume information supporting routine operations, training and military exercises, special activities, crisis, situational awareness, weapons targeting, intelligence, and the transition to and conduct of operations short of nuclear war.

The Wideband Global SATCOM (WGS) system, previously known as the wideband gapfiller satellite system, is a high-capacity communication satellite. WGS phased arrays support next generation DoD SATCOM capability Due to the early loss of a MILSTAR satellite, DOD committed to the purchase of 4 AEHF satellites plus one spare. WGS-1 with its 2.4 Gbit/s wideband capacity, provided greater capability and bandwidth than all the DSCS satellites combined.[6]. Until the future Advanced-EHF replacement to the MILSTAR comes on-line with its capability to transmit 1 Gbps, short-term solutions to the military's bandwidth shortfall would be needed, such as the Wideband Gapfiller, a lesser robust interim solution to AEHF, Global Broadcast System, and leasing options.

SSC is proud to be in a long-term relationship with Boeing on this important mission providing safe and secure critical communications, said Erik Eliasen, Vice President of National Security Space Programs for SSC Space US. Select a Satellite To Point to. Additionally, the Satellite Control Network will also use the WGS in a similar manner as the DSCS III constellation is used to route ATM packets through the Defense Information Systems Agency (DISA) "cloud" to establish command and control streams with various satellite constellations. Tactical forces rely on WGS to provide high-capacity connectivity to the Defense Information Systems Network (DISN). Live World Map of Satellite Positions - In-The-Sky.org The WGS-2 satellite, which was designated as USA-204, entered service in August 2009. Delta IV is an orbital launch vehicle equipped with 5m-diameter payload fairing and three CCBs, which are powered by a Rocketdyne RS-68 engine. Each WGS satellite provides service in both the X and Ka frequency bands, with the unprecedented ability to cross-band between the two frequencies onboard the satellite. The WGS satellites make use of modern satellite communications systems such as phased array antennas and digital signal processing technology to create a powerful architecture with a high degree of flexibility. WGS augments the one-way Global Broadcast Service (GBS) service through new two-way Ka-band service. Together these assets will provide wideband services during the transition period between today's systems and the advent of the Objective X/Ka wideband system or Advanced Wideband System (AWS), which has merged with Transformational Communications System (TCS), in 2008-2009. Satellite Dish Pointer with Google Maps. The WGS Fleet is controlled by four Army Wideband Satellite Operation Centers that receive telemetry and send commands to up to three satellites per center. The Boeing 702 uses advanced technologies in propulsion, power generation and thermal control, and can connect X- and Ka-band users within the coverage field of view via reconfigurable antennas and a digital channeliser. WGS Space Vehicles (SVs) are the Department of Defense's highest capacity communications satellites.
